LONDON — Another royal wedding is in the cards in Britain this year. Buckingham Palace announced Monday that one of Queen Elizabeth II's granddaughters, Princess Eugenie, will marry her long-term boyfriend, Jack Brooksbank.

The couple was introduced by friends during a ski break in Verbier, Switzerland, and have been dating for more than six years. They got engaged in Nicaragua earlier this month, the palace said.

Eugenie, 27, is the daughter of the queen's son Prince Andrew the Duke of York, 57, and his ex-wife, Sarah Ferguson, the Duchess of York, 58.

“The Duke and Duchess of York are delighted to announce the engagement of Princess Eugenie to Mr. Jack Brooksbank,” the palace said in the statement.

“The wedding will take place in the Autumn of 2018 at George's Chapel in Windsor, with further details to be announced in due course.”

St. George's Chapel, the mini-cathedral at Windsor Castle, will be busy this year: it's also the venue for the much-anticipated May wedding of Prince Harry, 33, and his fiancée, American actress Meghan Markle, 36.

Engagement photos of Eugenie and Brooksbank were taken in the Picture Gallery at Buckingham Palace, where Eugenie, wearing an Erdem dress and Jimmy Choo pumps, showed off her ring, a padparadscha sapphire (a pinkish orange gem) surrounded by diamonds.

The son of an accountant, Brooksbank, 31, was educated at a posh British school and grew up among the upper-class, aristocratic socialites who hang out with the young royals. Instead of college, he went into the restaurant and bar industry, and first worked as a bartender.

He's been the manager of Mahiki, a tropical-themed Mayfair nightspot for the rich and famous, including Eugenie's cousins, Princes William and Harry. And since 2016, he's worked as a U.K. brand representative for Casamigos Tequila, the spirits brand co-founded by George Clooney.

The couple traveled to the queen's retreat, Balmoral Castle in Scotland, during Prince Harry's 32nd birthday celebration in September 2016 to ask the queen to give them her blessing to get married, British media reported at the time.

HRH - 'We are overjoyed at the news today that Eugenie and Jack have got engaged. Jack is an absolutely outstanding young man and Eugenie and he have got to know each other over a number of years, and I'm really thrilled for them.'

Eugenie is eighth in line to the throne — and will move down to ninth when Prince William's third child is born in April — so technically, she doesn't need the queen's permission to marry. But she is close to her grandmother and would be expected to consult her before making a public announcement.

Eugenie's older sister, Princess Beatrice, 29, had been expected to announce her engagement to her American-born boyfriend, Dave Clark, a few years ago but they broke up in 2016. Beatrice is expected to play a prominent role in her sister's wedding.

The princesses are two of the 91-year-old queen's eight grandchildren, with her now-retired husband, Prince Philip, 96.

It is not clear yet whether Brooksbank will be given a title by the queen on the day of the wedding, as is typical when a princess marries a non-royal.

It's also unclear where they will live, but one possibility is a cottage or apartment at Kensington Palace, where they'd join her royal cousins.

The York princesses are the daughters of the queen's second-eldest son and "Fergie," divorced since 1996, who are still close and living in the same house, Royal Lodge. (They've even been subjected to will-they-remarry rumors in recent years.)

Although Beatrice and Eugenie are relatively high up in the royal succession, neither is expected to ever reign.
